Description
Technical field
The present invention relates to a kind of motor, particularly relate to a kind of cylinder pancake engine.
Background technique
Be a kind of symmetrical rock-steady structure because cylinder is horizontally-opposed, and center of gravity is low, therefore, stability, running smoothness and can be handling good.But the horizontally-opposed body that causes of cylinder is wider, thus and be unfavorable for layout.Application number be 201320477517.0 Chinese patent disclose a kind of horizontally-opposed four cylinder engine, four cylinder body horizontally-opposed both sides being contained in crankcase between two, four Carburetors are contained on four cylinder body suction ports by flange respectively; Manipulating mechanism of oil throttle is between four Carburetors, is controlled the aperture of four carburetor throttle butterfly valves by a valve rocker, two pull bars, two connecting rods and four connecting levers be fixed in the rotating shaft of four carburetor throttle butterfly valves simultaneously.Although this motor compact structure, volume is little, and rate of fault is high, and functional reliability is poor.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, the cylinder pancake engine of reliable operation.
The object of the present invention is achieved like this, a kind of cylinder pancake engine, comprise the bent axle be set in parallel on casing, camshaft and transmission shaft, bent axle both sides are horizontally-opposed is provided with the identical cylinder of quantity, camshaft both sides are respectively equipped with the cam that quantity is homonymy cylinder twice, each cam and a corresponding valve rocker, valve rocker is arranged in pitman arm shaft by axis hole, two valve rockers that homonymy is adjacent are arranged in same pitman arm shaft, pitman arm shaft is arranged on cylinder cylinder head, the rear end of valve rocker is connected with cam with hydraulic tappet by push rod, the front end of valve rocker is connected with valve, an inlet hole of the corresponding cylinder cylinder head of two valves that homonymy is adjacent and an exhaust port.
A driving mechanism for motor, comprises transmission shaft and driven tooth, also comprises butterfly bullet pad, butterfly bullet base and stop wheel hub, and driven tooth, stop wheel hub, butterfly bullet base A, butterfly bullet pad, butterfly bullet base B are set on transmission shaft successively; Wherein, driven tooth and transmission shaft are Spielpassung, and stop wheel hub circumference is fixed on transmission shaft, and butterfly bullet pad and butterfly bullet base and transmission shaft are Spielpassung, are curved face contact between stop wheel hub and driven tooth; Wherein, the curved surface A that the end face of stop wheel hub is formed for having the ratchet A that extends in the axial direction, the end face of driven tooth is the curved surface B with the ratchet B coordinated with ratchet A.
Sheathed driven tooth, stop wheel hub, butterfly bullet base A, butterfly bullet pad, butterfly bullet base B successively on transmission shaft, can avoid occurring " skiddings " when rotating member is subject to external impacts time and to dally phenomenon.
When transmission system normally works, follower rotates forward, owing to being curved face contact between follower and stop wheel hub, thus drive stop wheel hub to rotate forward, and stop wheel hub and transmission shaft axial restraint, then transmission shaft can be driven to rotate forward, and then the rotating member be connected with transmission shaft is rotated forward.When rotating member is subject to the impact of external force, stop wheel hub and driven tooth relative movement, play buffer function, due between transmission shaft with stop wheel hub for curved surface is connected, an axial rebounding force can be produced when stop wheel hub and driven tooth generation relative movement, this axial rebounding force to be passed on butterfly bullet pad and to be absorbed by butterfly bullet pad, absorbs rear propeller shaft and continues to drive stop wheel hub to rotate forward, thus driven rotary component proper motion.Both protect bent axle, turn avoid the danger of rotating member generation skid.In addition, according to situation and the loading condition of born external force, the quantity of butterfly bullet pad can be 1 also can be multiple.
In order to increase stability further, ratchet A and ratchet B has three respectively and is evenly distributed on the end face of stop wheel hub and driven tooth.
Better in order to make at cushioning effect further, between the side of the ratchet A matched and the side of ratchet B, there is space, between the bottom surface of ratchet A and the end face of ratchet B, there is gap.
In order to make structure compacter further, the gap between the bottom surface of ratchet A and the end face of ratchet B is 0.9-1.1mm.
In order to realize axial limiting, transmission shaft being provided with step surface, being equipped with an isolating ring be set on transmission shaft with step surface, isolating ring is positioned at the side of butterfly bullet base B.
In order to increase the life-span of transmission shaft further, the arc surface A of step surface to be radius be R, isolating ring has the arc surface B that radius is r, and arc surface A matches with arc surface B.Such setting can make in transmission shaft working procedure, and when there is interaction force between isolating ring and transmission shaft, this active force can be disperseed; The impact force of isolating ring to transmission shaft step surface will be reduced like this, transmission shaft can not be caused to suffer damage, crack, the working life of transmission shaft can be increased.
In addition, the end face of isolating ring and the step surface of transmission shaft are arranged to curved face contact, the area of contact of isolating ring and transmission shaft can also be ensured while the size that can reduce step surface, decrease the weight of driving mechanism on the whole, and then decrease the weight of motor.
Preferably, the radius r of the radius R >=arc surface B of arc surface A.Due in the process of transmission shaft work, the end face of isolating ring is a dynamic contact process with contacting of the step surface of transmission shaft, so the radius r being arranged to the radius R of arc surface A to be more than or equal to arc surface B can ensure to ensure maximum area of contact in dynamic contact process.In order to adjust the axial distance of transmission shaft further, transmission shaft is also arranged with axle sleeve, axle sleeve is arranged between isolating ring and butterfly bullet base B.Wherein, axle sleeve can be one also can be multiple, and such setting can not only adjust the axial displacement of transmission shaft, and some distances can also be reserved on transmission shaft, when needs during sheathed miscellaneous part, can take off axle sleeve on transmission shaft, the component that fit on needs.
